Odor from industries is a growing problem as cities are expanding closer to industrial areas. The production at food processing industries, fish factories, biodiesel plants and the like can create odors that might be a nuisance to the surrounding area. Odor control systems has thus become important to industries located closed to urban areas.

The HITEMA chillers are designed to freezing and cooling foods and beverage to avoid bacterial load issues and to maintain the correct temperature during the processing and the storage to avoid risks for human health. Beer breweries, pasteurization plants, bottling lines, distilleries and others, for hygienic needs, we are able to supply our units with covering and hydraulic circuits in stainless steel.

According to the International Committee on Illumination CIE recommendations, luminance should be monitored as the luminance contained within in a conical field of view, subtending an angle of 20º. It is recommended that a luminance photometer is mounted in the tunnel approach road approximately 120 - 200 metres from the portal, depending on the approach speed of the vehicles and their stopping distance. The purpose of monitoring the luminance at the portal is to adjust the level of light intensity inside...

Introduction
Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l: 0.5 – Japan, Russia; 1 – Argentina, Australia, Brazil, China, EC; 2...

Introduction
The mercury concentration in crude oil and petroleum products can vary in a wide range of less than 0.1 ppb to dozens ppm. Direct mercury determination in crude oil and petroleum products at the range above 5 ppb is covered by ASTM D7622-10(2015) "Standard test method for total mercury in crude oil using combustion and direct cold vapor atomic absorption method with Zeeman background correction". Mercury determination in naphtha and light petroleum products (condensate, gasoline and diesel fuel) at a...

INTRODUCTION
Quantitative determination of the total mercury content in filtrates of wash-off samples from the surfaces of walls, floors, equipment, and other facilities of m anufacturing areas is an effective method for the occupational safety monitoring.

Direct atomic absorption mercury determination (without any pre-treatment procedures) in food is complicated by its organics matrix. That is the reason why almost all AAS methods of mercury determination in foodstuff include sample digestion by acids.

IntroductionMercury is one of the most toxic trace contaminant naturally occurring in the coals. During the coal combustion process at the coal-fired power plants mercury is released into the environment. To manage effectively the stack gas cleaning process, it is necessary to know the mercury content in the coal, and also in stack gas, liquid and solid wastes.

With regard to the quality and safety of drugs, authorities worldwide set high standards for the pharmaceutical industry. To ensure these high quality and safety standards, reliable instruments and methods are needed.
